Now we have to check if all the connectors are working properly.
How to test your psu power outlet? If the PSU turns on in the previous test, that means it isn’t dead. If it rotates, we can proceed to the next step.
If it doesn’t, then most likely your power supply unit is dead.
Plugin the power socket and turn on the power connection.Īt this point, the fan should rotate.After inserting, place the 20/24 pin connector undisturbed.(Make sure the PSU is disconnected from the socket before doing this). Take the paper clip, and insert one end into the green pin, and the other end to any black pin.The green pin is usually located at pin 15. Notice that there is 1 green pin, some red, blue and black pins. Then disconnect the power supply unit from the CPU by removing the screws. Unplug the PSU connector from the motherboard.Open the CPU back cover to expose the power supply.Firstly, we shut down the computer and disconnect power from the wall socket by removing the plug.Before doing these operations, we should ground ourselves to prevent any unwanted electrical surges that can damage the components. If the clip is coated with paint, we have to remove paint from the two ends of the clip, and the metal portion will come out. Testing power supply with multimeter is a common thing. However, we can’t check if it’s working correctly, and to do that we need a multimeter. This is an easy way to identify if the power supply turns on or not. Check the individual pins (check psu health with a testing unit like multimeter).Check if PSU turns on or not (with a paper clip).Remove the motherboard power connector from the computer’s power supply. But how to test psu of your computer? There are two basic methods to check if the computer power supply is working correctly.
Testing hdd disk speed, power supply, power cord, or other units of a PC is great for clearing out issues and make room for improvements. The green pin is the 4 th pin from the right side. Take the connector while facing the connecting clip towards your face. If, however, the wires are colored the same, there’s an easy way to locate the green pin. There is only 1 green pin located at pin 15. The green connector is the main ON connection. These supply 5V, 12V, and 3.3V respectively, both positive and negative. There are red, blue, orange connectors for voltage supply. The gray connector is essentially a voltage level checker, that determines if the voltage is adequate. The black connectors work as a ground unit. Inside the connector, we can see wires with multiple colors. The 20/24 pin connector supplies power from the PSU to the motherboard components like processor, memory, and other parts directly. Almost all the computer case or pc case comes with a power supply. 20-Pin and 24-Pin Power Connectorīefore starting the procedures, it’s better to have an idea of a 20-pin or 24-pin power connector, as the testing process depends on it. So, a power supply test should be done sincerely. On the outside of the PSU, we can see a power supply fan that acts as a cooler for the CPU and PSU, a wall-socket connection, and most importantly, a 20-pin or 24-pin connector to attach the PSU with the motherboard. The power supply unit consists of some regular electric components like a transformer to increase or reduce voltage level, a rectifier that converts AC into DC voltage, voltage regulators to control the output voltage as needed. It converts AC power from household inlets and then converts them to DC power as needed for computer components like CPU, graphics card, etc to run effectively. PSU (Power supply unit) is the main unit through which electrical power is delivered to the CPU of a computer and then distributed through the power connector or power cable. To test the computer power supply, we must learn about it.
But how to test power supply? In this article, we’re going to discuss how to test the computer power supply with multiple methods. For many problems, checking the power supply can bring out the solutions very easily. An adequate power supply is a must for systems to run seamlessly, and many problems occur if the power supply unit fails to provide sufficient voltage levels based on the power consumption. The computer power supply unit (PSU) is one of the biggest pieces of hardware that directly affects user performance.
